In Eldarin Roots and Stems appear the roots "? UK, UKLA" (without any given significations, except for being one of the opposites of AYA).[3] It has been suggested that "the queried stem uk in this note is perhaps the same as later UK 'nasty'".[4][note 1]

Notes

↑ Note that the two different transcriptions have been rendered from the reading of the same manuscript: "? uk: ukla" in Vinyar Tengwar 49 and "? UK, UKLA" in Parma Eldalamberon XVII. Perhaps the latter was editorially changed to the standardized form given to roots.
